APPLIcA'ro-n.

Application filed June-14 1922. Serial No. 568,138.

To all whom it may concern:

Be it known that I, FERDINAND W. NI- TARDY, a citizen of the UnitedStates, re siding at Brooklyn, in the county of Kings,

5 State of New .York, have invented certain new and useful Improvementsin Applicators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to an applicator or fountain pencil adapted tocontain medicated solutions such as tincture 'of iodine '15 andpermitting the effective application of such solutions.

Iodine solutions, which are employed in surgical and medical practice asan antiseptic in treating wounds and as a counterirritant in reducingswellings and the like, have the disadvantage of discoloring the fingersof the user and of attacking various materials with which they maycontact. The use of ordinary containers such as bottles for iodinesolutions and the application of the solution with swabs of absorbentcotton are to be avoided, therefore, as far as is possible. Ampules ofglass containing small quantities of the solution and having swabs ofcotton attached into which the iodine is absorbed when the glass isbroken have been suggestedheretofore, but while such devices arerelatively inexpensive, they are not entirely satisfactor l It is theobject of the present invention to provide a simple and inexpensiveapplicator which has numerous advantages, among which are capacity, easeof application andprevention of leakage.

Other objects and advantages of the invention will be apparent as it isbetter understood by reference to thekfollowing specification andaccompanying drawing, in which Fig. 1 is a longitudinal section throughthe applicator with the capin place to seal the outlet;

Fig. 2 is asrmilar view of the applicator;

with the cap removed; 0

ing the feed passages through which the solution is delivered; and

Figs. 4, 5 and 6 are-sectlons on the lines 4-4, 5-5 andG-G of Fig. 3.

Referring to the drawing, 5 indicates the Fig. 3 is a longitudinalsection illustrat-.

fountain of the applicator which may be constructed of suitable materialsuch as glass, hard rubber or a phenol condensation product. Thefountain is preferably cylindrical in form, open at one end, and ofsufficient length to provide'a reservoir of desired capacity. A closureor stopper 6 is inserted in the open end of the fountain and ispreferably provided with a flange 7 which abuts the end of the fountain.The flange should extend slightly beyond the edge of the fountain sothat it may be grasped by the fingers of the user. i The stopper 6 isdesigned to permit the flow of liquid from the fountain, to serve 7 as aswab or brush and to cooperate with a cap 8 for the purpose of securelysealing the passage through which the liquid escapes. xreferably thestopper is constructed of soft rubber and is provided with twoconverging passages 9 so that in whatever position the applicator isheld air may enter' the fountain as the liquid flows therefrom.

At the point where the two passages come together forming a singleoutlet 10, the stopper, which is otherwise substantially circular insection, is provided with thickened walls or swells 11 which are adaptedto be engaged by a constricted portion 12 of the cap 8. The cap thuspinches the stopper at the point indicated and closes the outlet 10.

To ensurea tight seal the'passages 9 are preferably triangular insection, forming a lens-shaped passage at their junction with its majoraxis perpendicular to the major axis of the eliptical section of thestopper at this point. Thus resistance to the flattening effect of thecap is reduced and resiliency is preserved so that the passage will openwhenthe cap is removed. The end of the stopper ispreferably circular insection and the wall is sufficiently thin to provide a soft and flexibleswab whereby the solution may be applied to a wound or other surface. f100 The flange 7 formsga stop against which the cap 8 abuts when inplace, thus ensuring proper cooperation of the constricted portion ofthe cap with the swells 11 on the stopper. The flange also serves ,tolimit the 10 position of the stopper with respect to the fountain 5 andmay be grasped by the user to prevent withdrawal of the stopper when thecap is removed. i y

In using the applicator the cap, which 110 normally prevents escape ofliquid, is withwill be prevented, by capillary action, from escaping.

From the foregoing description it will be observed that I have provideda compact and handy applicator which may be used without soiling thefingers. Sufficient solution may be provided for a number ofapplications. The soft rubber swab will not harden as cotton swabs doafter contact with the-iodine, and the device may be used as long as thesupply of solution is available. Waste of material by absorption in theswab as is common in a plicators heretofore in use is prevented. nly somuch of the solution as is necessary need be utilized, whereas inampules the solution is lost if not utilized at once.

Various changes'may be made in the form and arrangement of the partswithout departing from the invention, and as will be readily understood,the applicator, although especially adapted for use with iodinesolutions, may be otherwise utilized.

I claim Y 1. In an applicator, the combination of a fountain, aresilient closure at one end thereof having a passage therethrough and acap having a constricted portion adapted to cooperate with the closureto seal the passage.

2. In an 'applicator, the combination of a fountain, a resilient closureat one end thereof having a passage therethrough and a cap adapted "topinch the closure and thereby seal the passage.

3. In an applicator, the combination of a fountain, a closure at one endthereof having passages therethrough converging to a common'outlet, anda cap adapted to pinch the closure and thereby seal the outlet.

4. In an applicator, the combination of a fountain, a resilient closureat one end thereof having passages therethrough of substantiallytriangular section converging to a shaped outlet passage, and means forapplying pressure to the closure in perpendicular directions to themajor axis of the passage.

7. In an applicator, the combination of a fountain, a resilient closurehaving a lensshaped outlet passage, and means for applying pressure tothe closure in perpendicular directions to the major axis of thepassage, the closure having swells cooperating with said means.

8. In an applicator, the combination of a fountain, a resilient closurehaving a lensshaped outlet passage and a cap having a constrictedportion adapted to compress the closure and close the passage. 7

9. In an applicator, the combination of a fountain, a resilient closuretherefor having a flange extending beyond the edge of the fountain and apassage permitting the escape of liquid from the fountain, and a capadapted to pinch the closure and thereby seal the passage, the flangeserving to fix theposition of the cap with respect to the closureandbeing adapted to be grasped the fingers of the user when the cap isremoved.

10. In 'an applicator, the combination of a fountain, a resilientclosure therefor having a flange extending beyond the edge of thefountain and a passage permitting the escape of liquid from thefountain, and a cap having a constricted portion cooperating with theclosure to seal the passage, the flange serving to fix the positionof'the cap with respect to the closure and being adapted to" be graspedby the fingers ofthe *tser when the cap is removed.

In testimony whereof I affix my signature.

FERDINAND VJ. NIIARDY.
